THREAD-SPINNING MACHINE.

Application filed May 17,

T 0 all whom it may concern Be it known that I, WILLIAM F. HAUP'r, acitizen of the United States, and a resident of the city of Orange,Essex County, New Jersey, have invented certain new and usefulImprovements in Thread-Spinning Machines, of'which the following is adescription.

My invention relates to thread spinning machines and more particularlyto improvements in the feed roller mechanisms which feed the finethreads downwardly from their respective spools to the spinning devicesin such machines.

In the manufacture of s un threads as it has heretofore been carrie on,considerable wastage of material results from the breakin of the finesingle threads which are finally spun into the finished thread. This isprincipally due to the. frictional wear on the threadby its engagementwith the feed rollers of the feed roller mechanisms and with thealigning or spacing bar which is located between and above such feedrollers, and to the fact that the ends .of' .the threads, once they arebroken, are likely to come in contact with and be drawn into the gearingof the feeding mechanism. The losses which are thus caused are veryappreciable, and where the spun threads are of high grade, expensivematerial, such as silk, are extremely serious. Moreover, much of thespun or finished thread manufactured at the present time is veryimperfect due to the wearing, catching and tearing of the thread byreason of its engagement with the feed rollers and the aligning andspacing bar referred to above.

Among the principal objects of my invention are to prevent ractlcallyall wastage and losses such as above described, and to roduce thefinished spun thread, especially in the case of silk thread, insubstantially perfect condition, or at least to a degree of perfectionheretofore unattained.

' My invention further contemplates an improved construction forattaining the foregoing objects, which is preferably in the form of anattachment capable of being readily :gplied to spinning machines now inuse. uch attachment is preferably removably mounted so as to be readilyreplaceable, and also preferably mounted for such adjustment as may benecessary to ensure the proper meshing or engagement of Specification ofLetters Patent.

the feed roller gears with the corresponding driving gear.

Other objects and features of my invention will be hereinafter morefully described and claimed.

In order that my invention may be more clearly understood, attention isdirected to' the drawing accompanying and forming a part of thisspecification, and in which:

Figure 1 is a view in front elevation, partly in section, of one of thefeed roller mechanisms of a silk spinning machine illustrating theapplication of my invention thereto; 1

Fig. 2 is a sectional view,'partly in elevation, taken on line, 2-2 ofFig. 1, looking in the direction of the arrows;

Fig. 3 is a sectional view taken on line 3', 3' of Fig. 1, looking inthe direction of the arrows;

Fig. 4 is an enlarged view in front elevation of one of the feed rollerears of the feed roller mechanism shown in Figs. 1, 2 and 3;

Fig. 5 is a View looking from the right in Fig. 4;

Fig. 6 is an enlarged central, longitudinal, crosshectional view of oneofthe feedroller gears with the feed roller mounted thereon; and

Fig. 7 is an enlarged detailed view, in elevation and partly in section,improved spacing and aligning bar and mounting.

Referring to the, drawing 1, 1 represent the fine,raw, silk threads,which are'respectively drawn, from spools (not shown) on the spinningmachine through tripper hooks (not shown), and then pass together downthrough the usual porcelain guide 2 which is supported on one end of anarm 3 adjustably secured to the usual vertical trip.- per rod 4, as bymeans of a collar 5 and set-screws 6. From the guide 2 the threads areconducted in the-'form of a single or combined thread 8 over horizontalfeed partly of my its rollers 7 and downwardly to the usual spin- Thehook or bar 9 while substantially horithe tripper rod 4 from itsproperly spaced pin-ions 10, 10, wk

.deleterious effects are zontal, has a slight downward inclination andserves as a guide to maintain the thread 8, in its several turns aroundthe feed rollers, and aligned. Two gears or rollers 7,.. 7, are normallyin engagement with and driven by a gear 11 fixed to the main horizontaldllVlDg shaft 12 of the ma- L The feed rollers 7, 7, feed roller gears10, 10 and the spacing and ali ning bar or hook 9 are all carried by arame 13 secured to the vertical tripper' rod 4 in a manner which will behereinafter described.

In case any of the fine raw threads 1, 1 breaks, the tension on thecorresponding tripper hook (not shown) is released, the latter drops andin turn releases the tripper rod 4, whereupon the tripper rod isautomatically raised or thrown up, carrying with it the frame 13, andthereby effecting the disengagement and separation of .the feed rollergears 10, 10 and the. driving gear 11, in a manner well understood. Inorder to ensure the proper engagement or meshing of the feed rollerpinlons 10, 10'with the driving gearll and also to render it extremelyeasy to replace the frame 13 and age, wear or other damage, adjustablyand the frame is also removably mounted form of a horizontal guide 14,and a collar 15 rigidly attached to the rod 45, as by means extension orbracket 17 a horizontal guide-we guide 14 engages. X

a screw 19 extends through a slot 2O in the extension 17 and is threadedinto the projection 14 of the.

frame 13. The loosening of screw 19 permits, the frame 13 to be easilyadjusted to gears 10, 10 with the sufiiciently to disengage the. samefrom the guide or rojection 14. I The frame 13 may according y be easilyand quickly replaced by a similar frame carrylng like parts, withoutinvolving the necessity of moving normal position in the splnningmachine.

' The feed, rollers heretofore used in mechanisms of the character shownand described erein, have usually been made of steel. 'Such rollers,however, are easily worn by silk and consequently the surfaces thereofquickly roughen and then wear, tear and catch the fine silkthreads orfibres. These further increased by ich serve to drive the feed,

the parts carried thereby in case of breakin shape and size with the'sary to frequently replace due tOxtllO'ffiCt that they The feed rollergears 10, 10 are rotatably mounted on steel rods 21 driven at one endinto the frame 13, and each of'these gears is provided with a long,laterally extending hub 22, which is irregular in cross-section andthrough which the rod 21 extends. Preferably the hubs 22 are square incross-section, although such crosssection may be hexagonal, ellipticalor of other non-circular shape. The hubs 22 are also preferablytapering, and thus when square in cross-section, as shown, they willhave the form of truncated yramids. The cylindrical feed rollers, 7, Qare made of porcelain and molded with axially extending openings whichsubstantially correspond gear hubs 22. Porcelain rollers provided withsuch 0 enings may be very readily molded. Eac of the rollers 7, 7 iskept in place on the re spectlve gear as by means of a. screw 23threaded into the outer end of the corresponding rod 21 and awasher 24disposed between the head of the screw and the adjacent ends ofthe gearhub and roller, the outer end portion of each roller preferably beingrecessed as indicated at 25 to receive the washer. and the head of thescrew. B-

reason of the cross-sectional shapeand taper of hubs 22 and the openingsthrough rollers 7, 7, the latter may be pushed tightly onto the gearhubs,-and when the screws 23 and against' anyrotary movement withrespect to the gears 10, 10 without danger of the rollers being broken.

Porcelain thread "aligning and spacing bars have heretofore been used inmechanisms of the character described herein, but prior to my inventionit has been necesthese bars as they are often broken. In addition to theexpense and trouble directly involved in such replacements, this resultsin serious losses insthe time of operation of machines vided with suchbars. The reason for the frequent breaking of these bars is probably areof small crosssection and have usual the feed roller frames by securingone end thereof directly in openings provided therefor in such frames.In order to obviate y been mounted on 2, 4, 5 and 6 and which prothisobjection, I provide a guiding and spacing bar 9 (referring to Fig. 7),preferably in the form of a hollow cylindrical tube provided with anouter hook end 26. This bar 9 is secured to the frame 13 by a headed rod27, preferably of steel or other metal, which extends through and fitsloosely within v the opening through the bar, andhead of the said rod,so that the bar will be securely held in the position shown. It will beapparent that transverse strains on the bar 9 will be transmitted to themetal rod 27 and that the danger of this bar being broken in theoperation of the machine is therefore extremely slight.

Another and a very important feature of my invention resides in theconstruction for effectually preventing the threads being drawn into thegearing in case,for example, any of the fine threads breaks and theframe 13 is automatically moved upwardly to disengage and space the feedroller gears 10, 10 from the driving gear 11-, as explained above.

\ For this purpose I preferably form the frame 13 as a hollow guard forthe feed roller gears 1.0, 10 and driving gear 12, by providing the samewith imperforate top and vertical side, and rear walls, and a verticalfront wall 30 having only a pair of circular openings 31, which are onlya very little greater in diameter than the feed rollers and throughwhich the inner end portions of these rollers extend. A hollow guard 32member formed with top, front and rear walls is also provided forcovering that portion of the driving shaft '12 below and adjacent thefeed rollers 7, 7, this member extending a considerabledistanceforwardly from the vertiml front wall 30 of the frame 13 substantiallyat fight angles thereto and being rigidly secured to the frame so as tomove upwardly therewith when the same is automatically raised by reasonof the thread breaking. Preferably, the guard member 32 is made anintegral part of the frame 13. The rear guard wall 33 of frame 13 isslotted at 34: so as to straddle .the shaft 12, and while the guardcomprising the frame 13 and member 32 is open at the bottom, all of itswalls, with the exceptions noted, are solid or imperforate, and all ofits vertical walls extend down a considerable distance below the shaft12. Accordingly, every part of the gearing and the driving shaft 12 withwhich broken ends of thread passing through the feed roller mechanismare at all likely to come into contact, are completely enclosed orcovered at all times, regardless of whether the frame 13 and the partscarried thereby are in lowered or raised position. Losses due to brokenthreads being drawn into and entangled with such gearing and drivingshaft are thus completely and effectually eliminated. In theconstruction shown, the frame 13 with its top, side, front and rearwalls and the guard member 32 formed integrally with the front wall 30of the frame, constitute an integral one-piece guard.

It will be seen that the frame 13 and the parts carried thereby, whichembody practically all features of my invention, comprise an attachmentcapable of being readily applied to spinning machines in use. Suchattachment when once applied to a machine is also capable of beingquickly and easily replaced and may be readily adjusted on such machinefor the purposes hereinbefore described.

While I have shown and described my invention as applied to a silkspinning machine, it is not limited in its application either tomachines forspinning silk thread form or construction. It is also to beunderstood that the various features of my invention are subject tovarious modifications and changes in the number, size, shape andarrangement of parts without departure from the spirit of my inventionand the scope of the appended claims.
